Izitho eziningi nezindlala zomzimba zimbozwe amasentimitha amaningana ethambo, imisipha, amafutha, isikhumba noma ezinye izicubu, okwenza ukuchayeka ekukhanyeni okuqondile kungenzeki, uma kungenzeki.Nokho, okunye okuhlukile okuphawulekayo amasende abesilisa.
Kuyafaneleka yini ukukhanyisa ilambu elibomvu ngqo emasendeni omuntu?
Ucwaningo lugqamisa izinzuzo ezimbalwa ezithakazelisayo zokuchayeka kokukhanya okubomvu kwesende.
Ukuzala Kukhuliswe?
Izinga lesidoda liyisilinganiso esiyinhloko sokuzala emadodeni, njengoba ukusebenza kwesidoda ngokuvamile kuyisici esikhawulelayo ekuzaleni ngempumelelo (kusuka ohlangothini lwendoda).
I-spermatogenesis enempilo, noma ukwakhiwa kwamaseli wesidoda, kwenzeka emasendeni, hhayi kude kakhulu nokukhiqizwa kwama-androgens kumaseli e-Leydig.Okubili kuhlobene kakhulu eqinisweni - okusho ukuthi amazinga aphezulu e-testosterone = izinga eliphezulu lesidoda futhi ngokuphambene nalokho.Akuvamile ukuthola indoda ephansi ye-testosterone enekhwalithi enkulu yesidoda.
Isidoda sikhiqizwa kumashubhu e-seminiferous of the testes, ngenqubo yezinyathelo eziningi ehlanganisa ukuhlukana kwamaseli amaningana nokuvuthwa kwalawa maseli.Ucwaningo oluhlukahlukene selusungule ubudlelwano bomugqa phakathi kwe-ATP/energy production kanye ne-spermatogenesis:
Izidakamizwa nezinhlanganisela eziphazamisa ukuguqulwa kwamandla e-mitochondrial ngokuvamile (okungukuthi, i-Viagra, i-ssris, ama-statins, utshwala, njll.) zinomthelela omubi kakhulu ekukhiqizweni kwesidoda.
Izidakamizwa/izinhlanganisela ezisekela ukukhiqizwa kwe-ATP ku-mitochondria (amahomoni egilo, i-caffeine, i-magnesium, njll.) kuqinisa izibalo zesidoda kanye nokuzala okuvamile.
Kakhulu kunezinye izinqubo zomzimba, ukukhiqizwa kwesidoda kuncike kakhulu ekukhiqizeni kwe-ATP.Uma kubhekwa ukuthi ukukhanya okubomvu ne-infrared kokubili kuthuthukisa ukukhiqizwa kwe-ATP ku-mitochondria, ngokocwaningo oluhamba phambili kulo mkhakha, akufanele kumangaze ukuthi amaza amaza abomvu/ayi-infrared abonisiwe ukuthi akhuphula ukukhiqizwa kwesidoda se-testicular nokusebenza kwesidoda ezifundweni ezihlukahlukene zezilwane. .Ngokuphambene, ukukhanya okuluhlaza okwesibhakabhaka, okulimaza i-mitochondria (ukucindezela ukukhiqizwa kwe-ATP) kunciphisa inani/ukuzala kwesidoda.
Lokhu akusebenzi nje kuphela ekukhiqizeni isidoda emasendeni, kodwa futhi ngqo empilweni yamangqamuzana amahhala e-sperm post-ejaculation.Isibonelo ucwaningo lwenziwe nge-in vitro fertilization (IVF), okubonisa imiphumela ephakeme ngaphansi kokukhanya okubomvu kuzo zombili izilwane ezincelisayo nesidoda sezinhlanzi.Umphumela ujule ikakhulukazi uma kuziwa ekuhambeni kwesidoda, noma ikhono 'lokubhukuda', njengoba umsila wamangqamuzana esidoda unikwa amandla umugqa we-mitochondria ekhanyayo ebomvu.
Isifinyezo
Ngokombono, ukwelashwa kokukhanya okubomvu kusetshenziswe kahle endaweni ye-testicle ngaphambi nje kokuya ocansini kungaveza ithuba elikhulu lokuvundiswa ngempumelelo.
Ngaphezu kwalokho, ukwelapha ngokukhanya okubomvu okungaguquki ezinsukwini zangaphambi kokuya ocansini kungase kwandise amathuba, ingasaphathwa eyehlisa amathuba okukhiqizwa kwesidoda okungavamile.
Amazinga e-Testosterone Angase Aphindwe Kathathu?
Kuye kwaziwa ngokwesayensi kusukela ngawo-1930 ukuthi ukukhanya ngokuvamile kungasiza abesilisa ukukhiqiza i-androgen testosterone eyengeziwe.Ucwaningo lokuqala ngaleso sikhathi lwahlola ukuthi imithombo yokukhanya ehlukanisiwe esikhunjeni nasemzimbeni iwathinta kanjani amazinga amahomoni, okubonisa ukuthuthuka okuphawulekayo ngokusebenzisa izibani ze-incandescent nokukhanya kwelanga okwenziwa.
Okunye ukukhanya, kubonakala sengathi, kuhle kumahomoni ethu.Ukuguqulwa kwe-cholesterol yesikhumba kuvithamini D3 sulfate kuyisixhumanisi esiqondile.Nakuba mhlawumbe okubaluleke nakakhulu, ukuthuthukiswa kwe-oxidative metabolism kanye nokukhiqizwa kwe-ATP kusuka kumaza amaza abomvu/ama-infrared kunemiphumela efinyelelayo, futhi evame ukubukelwa phansi, emzimbeni.Phela, ukukhiqizwa kwamandla eselula kuyisisekelo sayo yonke imisebenzi yokuphila.
Muva nje, kwenziwa ucwaningo ngokuchayeka elangeni, okokuqala emzimbeni, okwandisa ngokuthembekile amazinga e-testosterone owesilisa nganoma yikuphi ukusuka ku-25% kuya ku-160% kuye ngomuntu.Ukuchayeka elangeni ngokuqondile kumasende nakuba kunomphumela ojule nakakhulu, okuthuthukisa ukukhiqizwa kwe-testosterone kumaseli e-Leydig ngesilinganiso esingu-200% - ukwanda okukhulu ngaphezu kwamazinga ayisisekelo.
Ucwaningo oluxhumanisa ukukhanya, ikakhulukazi ukukhanya okubomvu, nomsebenzi wamasende wezilwane seluyiminyaka engaba ngu-100 manje.Ukuhlolwa kwasekuqaleni kugxile ezinyonini zesilisa nezilwane ezincelisayo ezincane njengamagundane, okubonisa imithelela efana nokwenza kusebenze ucansi kanye nokuphindaphinda.Ukuvuselela amasende ngokukhanya okubomvu kuye kwacwaningwa cishe iminyaka eyikhulu, ngezifundo ezikuxhumanisa nokukhula kwamasende okunempilo kanye nemiphumela yokuzala engcono cishe kuzo zonke izimo.Ucwaningo lwakamuva lwabantu lusekela ithiyori efanayo, lubonisa imiphumela emihle engaba namandla uma iqhathaniswa nezinyoni/amagundane.
Ingabe ukukhanya okubomvu kumasende kunemiphumela emangalisayo ku-testosterone?
Umsebenzi wamasende, njengoba kushiwo ngenhla, uncike ekukhiqizeni amandla.Nakuba lokhu kungashiwo cishe nganoma yisiphi isicubu emzimbeni, kunobufakazi bokuthi kuyiqiniso ikakhulukazi kumasende.
Ichazwe kabanzi ekhasini lethu lokwelapha ukukhanya okubomvu, indlela okusebenza ngayo amaza amaza abomvu okuthiwa ivuselela ukukhiqizwa kwe-ATP (engase icatshangwe njengohlobo lwemali yamandla eselula) ohlelweni lwethu lokuphefumula lwe-mitochondria (bheka ku-cytochrome oxidase - i-enzyme ethatha izithombe - ukuze uthole ulwazi olwengeziwe), ukwandisa amandla atholakalayo kuseli - lokhu kusebenza kumaseli e-Leydig (amaseli akhiqiza i-testosterone) kakhulu.Ukukhiqizwa kwamandla kanye nokusebenza kwamaselula kuyalingana, okusho ukuthi amandla amaningi = ukukhiqizwa kwe-testosterone eyengeziwe.
Ngaphezu kwalokho, ukukhiqizwa kwamandla omzimba wonke, njengoba kuhlotshaniswa / kulinganiswa ngamazinga e-hormone yegilo asebenzayo, kwaziwa ngokuvuselela i-steroidogenesis (noma ukukhiqizwa kwe-testosterone) ngqo kumaseli e-Leydig.
Enye indlela engaba khona ihlanganisa isigaba esihlukene samaprotheni athatha izithombe, aziwa ngokuthi 'amaphrotheni e-opsin'.Amasende omuntu maningi ikakhulukazi anezinhlobonhlobo zalawa ma-photoreceptor akhethekile afaka i-OPN3, 'enziwa isebenze', njenge-cytochrome, ikakhulukazi ngamaza okukhanya.Ukukhuthazwa kwala maprotheni amasende ngokukhanya okubomvu kudala izimpendulo zamaselula ezingase ekugcineni ziholele ekwandeni kokukhiqizwa kwe-testosterone, phakathi kwezinye izinto, nakuba ucwaningo lusasezigabeni zokuqala mayelana nalawa maprotheni kanye nezindlela ze-metabolic.Lolu hlobo lwamaprotheni athatha izithombe luyatholakala nasemehlweni futhi, ngokuthakazelisayo, nasengqondweni.
Isifinyezo
Abanye abacwaningi bacabanga ukuthi ukwelapha ukukhanya okubomvu ngokuqondile emasendeni isikhathi esifushane, esivamile kungakhuphula amazinga e-testosterone ngokuhamba kwesikhathi.
Lokhu kungase kubangele umphumela ophelele emzimbeni, ukukhulisa ukugxila, ukuthuthukisa isimo sengqondo, ukukhulisa imisipha, amandla amathambo kanye nokunciphisa amafutha omzimba amaningi.
Uhlobo lokuchayeka kokukhanya lubalulekile
Isibani esibomvuingavela emithonjeni ehlukahlukene;iqukethwe ku-spectra ebanzi yokukhanya kwelanga, izibani eziningi zasekhaya/zasemsebenzini, izibani zomgwaqo nokunye.Inkinga ngale mithombo yokukhanya ukuthi futhi iqukethe amaza aphikisanayo afana ne-UV (uma kunokukhanya kwelanga) kanye nohlaza okwesibhakabhaka (esimweni samalambu amaningi asekhaya/asemgwaqweni).Ukwengeza, amasende azwela kakhulu ukushisa, kakhulu kunezinye izingxenye zomzimba.Asikho isidingo sokusebenzisa ukukhanya okuzuzisayo uma ngesikhathi esisodwa ukhansela imiphumela ngokukhanya okuyingozi noma ukushisa okweqile.
Imiphumela yokukhanya okuluhlaza okwesibhakabhaka ne-UV
Ngokwemetabolism, ukukhanya okuluhlaza okwesibhakabhaka kungacatshangwa njengokuphambene nokukhanya okubomvu.Nakuba ukukhanya okubomvu kuthuthukisa ukukhiqizwa kwamandla eselula, ukukhanya okuluhlaza okwesibhakabhaka kuyawenza kubi nakakhulu.Ukukhanya okuluhlaza kulimaza ngokukhethekile i-DNA yeseli kanye ne-enzyme ye-cytochrome ku-mitochondria, kuvimbele ukukhiqizwa kwe-ATP ne-carbon dioxide.Lokhu kungaba kuhle ezimeni ezithile ezifana nezinduna (lapho amagciwane ayinkinga ebulawa), kodwa ngokuhamba kwesikhathi kubantu lokhu kuholela esimweni esingasebenzi ngendlela esifana nesifo sikashukela.
Ukukhanya Okubomvu vs. I-Sunlight kumasende
Ukukhanya kwelanga kunemiphumela eqondile enenzuzo - ukukhiqizwa kwevithamini D, isimo sengqondo esithuthukisiwe, ukwanda kwamandla e-metabolism (ngemithamo emincane) nokunye, kodwa akukhona ngaphandle kokubi.Ukuchayeka kakhulu futhi awulahlekelwa nje kuphela zonke izinzuzo, kodwa udala ukuvuvukala nokulimala ngendlela yokushiswa yilanga, ekugcineni kube nomthelela womdlavuza wesikhumba.Izindawo ezizwelayo zomzimba ezinesikhumba esincane zivame kakhulu kulo monakalo kanye nokuvuvukala okuvela ekukhanyeni kwelanga - ayikho indawo yomzimba ngaphezu kwamasende.Izodwaimithombo yokukhanya okubomvunjengama-LED afundwa kahle, abonakala engenawo amaza aluhlaza okwesibhakabhaka nama-UV ayingozi ngakho-ke abukho ubungozi bokushiswa yilanga, umdlavuza noma ukuvuvukala kwamasende.
Ungawashisi amasende
Amasende wesilisa alenga ngaphandle komzimba ngesizathu esithile - asebenza kahle kakhulu ku-35°C (95°F), okuyi-degrees amabili agcwele ngaphansi kwezinga lokushisa lomzimba elivamile elingu-37°C (98.6°F).Izinhlobo eziningi zamalambu namalambu asetshenziswa abanye ekwelapheni ukukhanya (njengama-incandescent, amalambu okushisa, amalambu e-infrared angu-1000nm+) akhipha ukushisa okukhulu ngakho AKUFANELE ukusetshenziswa kumasende.Ukushisa amasende ngenkathi uzama ukufaka ukukhanya kunganikeza imiphumela engemihle.Okuwukuphela 'okubandayo'/imithombo ephumelelayo yokukhanya okubomvu ama-LED.
Umugqa Ongezansi
Ukukhanya okubomvu noma kwe-infrared kusuka ku-Umthombo we-LED (600-950nm)icutshungulwe ukuthi isetshenziswe kuma-gonads wesilisa
Ezinye zezinzuzo ezingaba khona zichazwe ngenhla
Ukukhanya kwelanga kungasetshenziswa futhi kumasende kodwa kuphela isikhathi esifushane futhi abunayo izingozi.
Gwema ukuchayeka kublue/UV.
Gwema noma yiluphi uhlobo lwesibani sokushisa/isibani se-incandescent.
Indlela efundwa kakhulu yokwelapha ukukhanya okubomvu isuka kuma-LED namalaser.Ama-LED abonakalayo abomvu (600-700nm) abonakala elungile.
